Facade sealing for East Ashling sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

After the work

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Brief window cleaners about newly sealed joints
  • Ask about asbestos in pre-2000 mastic
  • Share access with other external trades
  • Avoid patch repairs on failed facade joints

Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed instead of soaking the joints.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down and cuts time on site.

About our facade sealing in East Ashling

External joints face UV, rain, temperature swings and building movement all year. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. We work on coping and flashing joints, perimeter joints where frames meet the structure and shopfront frames, and the failures we are asked to look at most are previous reseals run over old sealant and facade joints cracked through the middle. Most enquiries from East Ashling start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

In the countryside around places like East Ashling, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We stand by our work with a 12-month guarantee. That covers our preparation and application.

Common questions from East Ashling clients

Can you work at a site such as Polthooks Farm Industrial Estate., by East Ashling?

Yes. Our area takes in East Ashling and its surroundings, with estates and business parks such as Polthooks Farm Industrial Estate. Included. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Is hospital work, at somewhere like Nuffield Health Chichester Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Is East Ashling in your area?

Yes. East Ashling falls within our area, and you can give us a call on 01277 525 020 or email drawings and photos to get started.

Can you just add new sealant on top?

No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.

How the job changes by surface

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather.

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface, often a low-modulus silicone or hybrid.

Doing it in-house

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Cost factors for facade joints

We price every job individually. The things that drive the figure:

  • The site’s rules and procedures
  • Travel to remote or island sites
  • The total length or number of joints
  • How accessible the joints are

A quote for facade joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

Details that help us quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • A wide shot and a close-up of the area
  • When you need the work done
  • Rough lengths or quantities, or drawings if you have them
  • How the joints are reached, and at what height

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Building and refurbishing in East Ashling

Central London is about 55 miles from East Ashling. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. East Ashling sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.

For contractors on a campus like University of Chichester, which lies south-east of East Ashling, facade and perimeter sealing has to fit around students and term dates. Projects at colleges like Chichester College (2.8 miles south-east of East Ashling) tend to run to term dates, so the mastic is planned tightly. For contractors at a school such as Funtington Primary School, sealing has to be finished before term starts.

Commercial clients in East Ashling

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

How a job runs

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. If others near East Ashling need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Warn occupants and staff about the work
  • Share your working hours and any access restrictions
  • Move anything stored against the joints
